解决：Error parsing HTTP request header、Invalid character found in method name、names must be tokens

服务日志突然报这个问题

o.apache.coyote.http11.Http11Processor   : Error parsing HTTP request header
 Note: further occurrences of HTTP request parsing errors will be logged at DEBUG level.

java.lang.IllegalArgumentException: Invalid character found in method name [SSH-2.0-OpenSSH0x0d0x0a...]. HTTP method names must be tokens

查阅了一些资料，说可能是请求头过大导致的问题，需要扩大其可传递请求头的大小

server.max-http-request-header-size: 1048576
